6.4/10Yellow.ai is an enterprise agentic AI platform that builds chat, voice and email agents to automate customer service and employee support across many channels.
Data last updated November 2026 · Our methodology
Overview
Yellow.ai, which started in 2016 as Yellow Messenger, sells its Nexus platform for building AI agents that handle customer experience (CX) and employee experience (EX) conversations. Teams build agents in a no-code builder or by describing them in natural language. An AI copilot handles testing and debugging. The conversational knowledge base answers questions from company documents. The platform covers more than 35 channels, including web chat, WhatsApp, SMS, email and voice, and the vendor claims support for more than 135 languages. Nexus VOX is its voice agent product. The multi-LLM design draws on more than 15 models. Other tools include User360 customer profiles, outbound campaigns, analytics and agent assist. There are more than 150 pre-built integrations, including Salesforce, Zendesk, HubSpot, Freshdesk, Genesys and NICE. Pricing has two levels. The Free plan includes one AI agent, two seats and 500 chat sessions a month, then charges $0.99 per resolution. The Enterprise plan is quote-only. AWS Marketplace listings put annual packages at about $10,000 and $25,000. The vendor lists SOC 2 Type II, ISO 27001, ISO 27701, HIPAA and PCI-DSS, with data hosting in several regions. The platform best suits large, multi-region enterprises that have technical staff. Its main limitation is delivery. Reviewers report implementations that stall, bots that lose context or misread intent, and support that suffers from account-team turnover. The company also cut about 30% of its staff in December 2025.
Our Rating
Who Yellow.ai is best for
Good fit
It automates customer service with AI agents on more than 35 channels and has agent assist plus Zendesk, Freshdesk, Genesys and NICE connectors.
Reviewers agree it is built for large organizations that run many channels and have compliance needs.
Less suited
PCI-DSS, SOC 2 and ISO 27001 certifications plus regional data hosting suit regulated firms.
The vendor lists HIPAA compliance.
It covers employee experience automation for internal support conversations.
It offers outbound campaigns and WhatsApp and web chat agents for customer conversations.
The employee support agents can handle internal helpdesk queries.
It is usable at this size, but quote-only pricing with an annual floor of about $10,000 and a heavy implementation load limit the fit.
Outbound campaigns and a Salesforce and HubSpot integration support some sales use, but the focus is service.
The free plan is small, and reviewers advise smaller teams to look at alternatives with published pricing.
There is no published mid-tier plan, so a startup moves straight from the free plan to an enterprise contract.
It is an enterprise platform, and paid packages start around $10,000 a year.
Pros & Cons
Pros
- More than 35 channels, and context carries over when a customer switches channel.
- A broad security portfolio (SOC 2 Type II, ISO 27001 and 27701, HIPAA, PCI-DSS) with data hosting in the US, EU and Asia.
- More than 150 pre-built connectors, including Salesforce, Zendesk, Genesys and NICE.
- Covers both customer-facing and employee-facing automation on one platform.
- A free plan with self-serve signup lets teams test the builder before talking to sales.
Cons
- No public price between the free plan and the quote-only Enterprise plan. Marketplace listings suggest about $10,000 a year as the floor.
- Reviewers report bots losing context and missing intents.
- Support complaints centre on poor communication and account-team turnover.
- Implementations can stall, and changing live journeys often needs engineering help.
- The December 2025 layoffs and the pending SPAC listing raise questions about continuity on multi-year contracts.
